Rapid Refresh Model Available

"The Americans have got one, so why haven't we?" came the very well made point at Metcheck Towers the other week. You see, there are some fantastic weather models which are available these days on t'internet, but the one thing which the UK has always lacked is a high resolution, rapid refresh model.

This is a model which is run every single hour of the day and takes in the latest radar, satellite and observations coming in from around the world. After all, there is nothing more annoying than looking at a forecast chart from a model and realising that it can't even seem to get the weather right at the moment regardless of a few hours ahead.

The HRRR model shows the forecast radar images, hourly snowfall forecast as well as cloud cover and the risk of seeing lightning strikes out to 36 hours ahead. The model is run hourly and the new images come through at around 35 minutes past each hour. At 3am, 6am, 9am, midday, 3pm, 6pm, 9pm and midnight the model is run out to 36 hours ahead, but all the other times it runs out to 21 hours ahead.

So "The Americans have got one, so why haven't we?"... Well, funny you should ask that, as now we have. The Metcheck HRRR model is now available online.
